To all wtom it may concern.' i Be it known that I, Jn-Lrns A. PriuKrNs,a

States of America, and

York and State of New Yorlghave invented certain new and usefulImprovements in Bearings for Rollers, of' which the following is aspecilication, such as will enable to which it appertains to make anduse the same. j

,This invention relates to roller bearings, v with a. particularreference to the 'use thereof in car journal boxes, as, lforinstance, inmy Letters Patent nf" the United States numbered 1,002,442, and

bearing 4date of September 5, 1911, with the distinction, however, thatmy present invene tion 1s adapted for use in journal boxes not providedwith the roller supporting tracks porting tracks is,

. in -the bottom of were provided;

a clearance'of the entire `supporting' element of two' straps, shown flionvergent for 'a portion of' their lengths supporting means bei shownin the said Letters Patent.

ome equivalent of the said roller suphowever, practically essentialwhere the rollers pass over open spaces the journal box, as shown, inorder toprevent the centrifugal eil'ect i upon the roller alining hallsat the rollerends which would occur if the rollers flew o ll" into spacewhere nosupporting means also to allow the rollers Ato re-alinethemselves by supporting them at changing points .in the lengthsthereof'while passing over such the angle of approaclrof the rollersbetween the journal and the' bearing members so gradual that the journalgets a bite on the rollers and the latter roll under the load Withoutany strain upon the cage or ball bearings'at the endsof the rollers.

Further, scale or foreign matter may lodge upon the rollers in theirplanetary movement, and. it is therefore advisable to' so form thesupporting element as to permit roller length to pery mit the ,escape ofsuch matter froxnthe rollers-into the box bott f this beinglmaccmplished Lin my pr'esentlform by making tlie and joined beneath th'roller-,bearing cage,v Jermitting the roller red 'to and, my roller gentirely independent of the box, no cha gelis required in the lattenoverthe conventinal formjnow in use other than' curving the ower portions.of the z t lis construction also re-al1nement aboverefe spaces, andalso to make i Y ,face concentric with vthe block and adapted to .thebox` in order to "capable of cndwise movement in, the

side lugs concentric. with -the journal of the axle. -I l y My inventionis fully set forth in the following specification, of whichtheaccompanying drawings from a part, in which theV separate parts aredesignated by thesarne reference characters in each of the views, and inwhich:m

igure 1 is a central, vertical, `longitudinal section through a car:journal box provided with my invention;

4Fig. 2 1s a section' on the line 2-2 of Fig.

f1', some of the rollers being omitted and none sectioned; l l

Fig. 3 is asection on the line 3-3 of F ig;

l, but showing the roller supporting meansV application I have shown a4car journal boxl a, of conventional or other form,I but prov1ded withthe usual side lugs a2 for use with the' conventional brass and wedgefrictional4 4 hearings, the lower portion curved concentric with the axcated in dotted lines in Fig. Zand said axle is provided with an endHange-2 and an inner shoulder Il in the usual manner.

Arranged about are va plurality of rollers @having anti-frictionalbearing blocks c2 at the ends thereof seated in corresponding: recessesin a cage c3 comprising end plates c4 and connecting ribs forms no parto1"- this invention.

yVVi'thin the box, above the journal of the axle, is-a block (Z,concaved on its lower sur-- journal and ser-vim:T asa bearing member forthe rollers c to take the load, said block being provided with siderecesses d?, as shown in Fig. 3, arranged ap'- projximately midway ofthe length of said receive the lugs a? of render said block in box, andpresent recesses (la .in the upper surpf" Said lugs said block is alsoprovided, in the .-OIIn, with four face thereof, two on each side of andclose .to the ends oi said block.

y esting in each of the recesses cls is the angularly bent end e el?each. of two straps e2 whlch vare substantially vertical from the thejournal of the axle b c5, but the specific 4cage construction :Wil

reference to Figs. 1, 3 and 4, it will be seen i that the strapsconverge toward the bottom of the axle and are joined at e in thevertical axial plane ol the axle, preferably integrally although notnecessarily, thus providing a bearin; r for the rollers which permits ofthe entire clearance of the latter in their planetary movement to permitscale or foreign matter to escape 'from the rollers and fall to therefuse receptacle in the box bottom'.

In assembling, the block Z and roller sup.

porting means e2 are introduced into the box from the open front end,and the block nl arranged in proper position with respect tothe lugs a2,after which the axle with the cage of rollers thereon is entered fromthe inner box end and passed through the supporting means c2, a dustguard j' beingv next installed if desired, but this l .ars no relationto the present invention, and I may also provide an axleendd'lnfustdevice f2 which is installed after the bearings are assembled in thebox, some sort of end-thrust beingpracticall)y essential in the use ol'roller hearings, and l also prefer to provide loating' cagecontrollers-f and f at the cage ends to take any cage endwise movementin a ,Ljlancing'and substantially anti-frictiomll manner, and, as shownin Fig. l, I prefer to slightly curve the upper surface ot' the blockrl., from front to rear, to permit a slight rocking' movementv thereoilto compensate for axle movement in the box due to irregularity oi trackand consequent vertical n'iovennrnt oi' the car provided with myinvention.

.lt will thus he seen that l provide a roller suiiortine device which isentirel inde.

pendent of the box, which permits a clearance of objectionable mattervtrom the rollers, which is quickly and easily installed, and

which is very inexpensive and adaptable to f conventional boxes in whichit is desired to substitute roller bearings for .the usual brass andwedge' frietional bearings, and which also permits the rollers torealine themselves in the event of their having been forced out"'various changes therein and thereover tof j meet varying,r conditionswithinthescope of the followin r claims.

` Having full I claim as new, and desire to secure by Letters Patent, isi l i 1. A car journal box, an axle therein, a series ot' rollers aboutsaid axle, a roller bearing member in the top of said box and 'adetachalile roller supporting strap having inwardly turned upperendsoverlying said member adjacent each end of said rollers.

Aucar journal box, an axle therein, a series of rollers about said axle,a roller bearing member in the top of 'said box, and a roller supportingstrap suspended from said member adjacent each end of said rollers, saidstraps 'being vertically arranged for a portion of their lengthsand'converging toward the lower side of said' axle.

3. A ear journal box, an axle therein, a series ot rollers about saidaxle, a roller bearing member in the top ot said box, and a rollersupporting,r member suspended there Vtrom, said supporting membercomprising a central lower portion havingr upwardly directed, Iivergent,arms connected therewith y described my invention, what and being'concentric with said axle beneath Y the horizontal, axial, plane of saidaxle.

4. A ear journal box, an axle therein, aseries oi rollers about said.axle, a roller bearing member in the top-ofsaid box provided withrecesses inv the upper surface thereof, and a roller. supporting strapa1'- ranged adjacent each end of said rollers and the Lipper ends ofwhich are inwardly turned and rest in corresponding recesses, saidstraps being joined beneath said axle at the centers of said rollers. j

In .testimony that I'claim the foregoingas my invention I have signed myname in presence of the subscribing witnesses this 10th day of March,1913.
